摘要
以北京部分城市道路扬尘为对象,研究了新型环保道路抑尘剂喷洒前后道路扬尘中PM10和PM2.5浓度的变化。结果显示,喷洒新型环保道路抑尘剂能够有效降低扬尘中PM10的浓度,对PM10的降尘效果为25%,对PM2.5也有一定的降尘效果,同时对大气中的氮氧化物有一定的吸附作用,说明该新型环保道路抑尘剂可有效抑尘,减少污染。
With the dust in some of city roads in Beijing as the research object, the change of PM10 and PM2.5 concentrations before and after spraying a new environment-friendly road dust suppressant was studied. The results showed that the new environment-friendly road dust suppressant could effectively reduce the concentration of PM10, with PM10 reduction effect of 25%. The dust suppressant could also reduce PM2.5 and absorb nitrogen oxides in the air. The new dust suppressant is thus efficient in controlling road dust and reducing pollution.
